Application filed Kay 10,

Theobject of this invention is to provide an improved flashing for usebetween a roof and a fire-wall, which is so arranged as to be ment ofthe roof and wall has occurred.

' A further object is to provide an improved interlocking flashing, onemember of which is mounted rigidly in a wall and the other member ofwhich is interlocked therewith and depends in inclined position over thejoint between the wall and a roof.

A further object is to provide an improved interlocking flashing asabove set forth in combination with a combined cant and settling stripattached to the roof and contacting with the wall in a manner to permitrelative movement therebetween so that effective provision is made forcovering the j oint' between the roof and wall irrespective of anysettling which may occur.

With these and other objects in view, my

invention consists in the construction, ar-

ran ement and combination of elements hereina ter set forth, pointedoutin the claim and. illustrated by the accompanying drawing, in which iigure 1 is a perspective view of my im-. proved device showing theseveral parts in their proper relative positions.

F i res 2 and 3 are sectional views showing t edevices in position forpractical use, the lattervview illustrating how the settling strip moveswith the root when settling occurs.

In the construction as shown the numeral 10 designates generallyafire-wall, 11 a rafter and 12 sheathing boards of a roof which isarranged somewhat below'the top of the wall and in abutting relationthereto. The numeral 13 is used to designate a flexible roof coveringover the sheathing boards.

In constructions of this kind it is very difficult to form a rain-tightjoint between the roof and fire-wall because settling or relativemovement is apt to occur and break the sealing of the joint. I haveprovided a flashing which will overcome this difliculty by permittingsome elements to move relative to the others, the water-proof elementsuch as the roof covering 13 moving therewith and still remaining inposition to cover the joint.

A strip 14 of wood is provided which extends lengthwise of the joint andhas one margin secured to the sheathin 12 at a point spaced somewhatfrom the wa l, as by nails formed at one margin with a lateral flange 191926. Serial lb. 107,967.

15. This strip 14 preferably is wedge-she and has oneface designated at16 directed t ig ward the wall so that it contacts for a con-.

siderable space therewith, but is not secured thereto. This strip may becalled a combined cant strip and settling strip, as it. has the usualfunction of a cant strip and further permits settling of the roofwithout breaking the joint. t is rather wide as compared with the usualcant strip, being six or eight inches in vertical width. The flexibleroof covering 13 is extended up the outerface of the strip 14substantially to the top. and is mopped thereto in a common manner.

lnterlocking flashing strips of sheet metal are provided and indicatedby the numerals 17 and 18. The horizontal strip 17 is laid betweencourses of brick or other members of the wall 10 and rigidly heldthereimit being in contact with elements of the wall. The strip 17 isalso formed with a series of apertures 20 which receive mortar or cementof the wall and assist in holding the strip rigidly in place. The strip17 is formed on its other margin with a downturned flange 21 terminatingin an inwardly directed hook flange 22 arranged horizontally and openingtoward the wall and slightly spaced therefrom. The horizontal strip 17is spaced a slight distance above the upper margin of the combined cantand settling strip 14. The strip 18 is formed at its upper margin with alateral flange 23 adapted to be received within the hook flange 22 ofthe horizontal strip and interlock therewith. The interlockin engagementis effected after the horizonta strip is in place and after the settlingstrip has been placed and the roof element 13 secured thereto, and itbrings the flashing strip 18 into substantial contact with the roofelement 13 along the upper margin of the settling strip 14:. Theinterlocking engagement is made permanent by pinching the hook flange 22upon the flange 23 by the use of pliers or other suitable tool.

This provides an effective means for covering the joint between the roofand wall, and if any settling of the roof occurs the settling strip 14,and with it the portion of roofin 5 movement may occur withoutafl'ecting the 11 joint. 1115 strip 14 preferably is provided with'proper the nails 15. v

I claim as myinventionpreformed holes 24 to receive I i '5 In a flashingdevice for use in protecting a 10 flange abutting the outer face of thewal and v a downturned inner marginal flange abutting the inner face ofsaid wall; the lower edge of the downturned flange terminating in ahorizpntally and inwardly directed hook flange, sald hook flangeproviding a channel opening toward said wall, and a. second striparranged in a substantially vertical position having its upper edge bentlaterally to provide a horizontal flange thereon received in the channelof said hook flange to interlock 20 therewith, as and for the purposesdescribed.
